Ubuntu MATE 22.04 LTS is the culmination of 2 years of continual improvement 😅 to Ubuntu and MATE Desktop. As is tradition, the LTS development cycle has a keen focus on eliminating paper 🧻 cuts 🔪 but we’ve jammed in some new features and a fresh coat of paint too 🖌 The following is a summary of what’s new since Ubuntu MATE 21.10 and some reminders of how we got here from 20.04. Read on to learn more 🧑🎓
Thank you! 🙇
I’d like to extend my sincere thanks to everyone who has played an active role in improving Ubuntu MATE for this LTS release 👏 From reporting bugs, submitting translations, providing patches, contributing to our crowd funding, developing new features, creating artwork, offering community support, actively testing and providing QA feedback to writing documentation or creating this fabulous website. Thank you! Thank you all for getting out there and making a difference! 💚
Ubuntu MATE 22.04 LTS (Jammy Jellyfish) - Mutiny layout with Yark-MATE-dark
Here are the highlights of what’s changed recently.
MATE Desktop 1.26.1 🧉
Ubuntu MATE 22.04 features MATE Desktop 1.26.1. MATE Desktop 1.26.0 was introduced in 21.10 and benefits from significant effort 😅 in fixing bugs 🐛 in MATE Desktop, optimising performance ⚡ and plugging memory leaks. MATE Desktop 1.26.1 addresses the bugs we discovered following the initial 1.26.0 release. Our community also fixed some bugs in Plank and Brisk Menu 👍 and also fixed the screen reader during installs for visually impaired users 🥰 In all over 500 bugs have been addressed in this release 🩹
Ubuntu MATE 21.04 was the first release to ship with a MATE variant of the Yaru theme. A year later and we’ve been working hard with members of the Yaru and Ubuntu Desktop teams to bring full MATE compatibility to upstream Yaru, including all the accent colour varieties. All reported bugs 🐞 in the Yaru implementation for MATE have also been fixed 🛠
Yaru Themes in Ubuntu MATE 22.04 LTS
Ubuntu MATE 22.04 LTS ships with all the Yaru themes, including our own “chelsea cucumber” version 🥒 The legacy Ambiant/Radiant themes are no longer installed by default and neither are the stock MATE Desktop themes. We’ve added an automatic settings migration to transition users who upgrade to an appropriate Yaru MATE theme.
Cherries on top 🍒
In collaboration with Paul Kepinski 🇫🇷 (Yaru team) and Marco Trevisan 🇮🇹 (Ubuntu Desktop team) we’ve added dark/light panels and panel icons to Yaru for MATE Desktop and Unity. I’ve added a collection of new dark/light panel icons to Yaru for popular apps with indicators such as Steam, Dropbox, uLauncher, RedShift, Transmission, Variety, etc.
Light and Dark panels
I’ve added patches 🩹 to the Appearance Control Center that applies theme changes to Plank (the dock), Pluma (text editor) and correctly toggles the colour scheme preference for GNOME 42 apps. When you choose a dark theme, everything will go dark in unison 🥷 and vice versa.
So, Ubuntu MATE 22.04 LTS is now using everything Yaru/Suru has to offer. 🎉
AI Generated wallpapers
My friend Simon Butcher 🇬🇧 is Head of Research Platforms at Queen Mary University of London managing the Apocrita HPC cluster service. He’s been creating AI 🤖 generated art using bleeding edge CLIP guided diffusion models 🖌 The results are pretty incredible and we’ve included the 3 top voted “Jammy Jellyfish” in our wallpaper selection as their vivid and vibrant styles compliment the Yaru accent colour theme options very nicely indeed 😎
If you want the complete set, here’s a tarball of all 8 wallpapers at 3840x2160:
Ubuntu MATE stuff 🧉
Ubuntu MATE has a few distinctive apps and integrations of it’s own, here’s a run down of what’s new and shiny ✨
Switching layouts with MATE Tweak is its most celebrated feature. We’ve improved the reliability of desktop layout switching and restoring custom layouts is now 100% accurate 💯
Having your desktop your way in Ubuntu MATE
mate-netbook from the default installation of Ubuntu MATE and
as a result the Netbook layout is no longer available. We did this because
mate-maximus, a component of
mate-netbook, is the cause of some
compatibility issues with client side decorated (CSD) windows. There are still
several panel layouts that offer efficient resolution use 📐 for those who need
MATE Tweak has refreshed its supported for 3rd party compositors. Support for
Compton has been dropped, as it is no longer actively maintained and
comprehensive support for picom has been added.
picom has three compositor options: Xrender, GLX and Hybrid. All three are
can be selected via MATE Tweak as the performance and compatibility of each
varies depending on your hardware. Some people choose to use
they get better gaming performance or screen tearing is reduced. Some just
like subtle animation effects
picom adds 💖
Recent versions of
rofi, the tool used by MATE HUD to visualise menu
searches, has a new theme system. MATE HUD has been updated to support this
new theme engine and comes with two MATE specific themes (
mate-hud-rounded) that automatically adapt to match the currently selected
You can add your own
rofi themes to
~/.local/share/rofi/themes. Should you
want to, you can use any
rofi theme in MATE HUD. Use Alt + F2
rofi-theme-selector to try out the different themes, and if there is
one you prefer you can set it as default by using running the following in a terminal:
gsettings set org.mate.hud rofi-theme <theme name>
MATE HUD uses the new rofi theme engine
Windows & Shadows
I’ve updated the Metacity/Marco (the MATE Window Manager) themes in Yaru to make
sure they match GNOME/CSD/Handy windows for a consistent look and feel across
all window types 🪟 and 3rd party compositors like
picom. I even patched how
picom render shadows so windows they look cohesive regardless of
toolkit or compositor being used.
Ubuntu MATE Welcome & Boutique
The Software Boutqiue has been restocked with software for 22.04 and
Firefox 🔥🦊 ESR (
.deb) has been added to the Browser Ballot in Ubuntu MATE Welcome.
Comprehensive browser options just a click away
41% less fat 🍩
Ubuntu MATE, like it’s lead developer, was starting to get a bit large around the mid section 😊 During the development of 22.04, the image 📀 got to 4.1GB 😮
So, we put Ubuntu MATE on a strict diet 🥗 We’ve removed the proprietary NVIDIA drivers from the local apt pool on the install media and thanks to migrating fully to Yaru (which now features excellent de-duplication of icons) and also removing our legacy themes/icons. And now the Yaru-MATE themes/icons are completely in upstream Yaru, we were able to remove 3 snaps from the default install and the image is now a much more reasonable 2.7GB; 41% smaller. 🗜
This is important to us, because the majority of our users are in countries where Internet bandwidth is not always plentiful. Those of you with NVIDIA GPUs, don’t worry. If you tick the 3rd party software and drivers during the install the appropriate driver for your GPU will be downloaded and installed 👍
NVIDIA GPU owners should tick Install 3rd party software and drivers during install
While investigating 🕵 a bug in Xorg Server that caused Marco (the MATE window manager) to crash we discovered that Marco has lower frame time latency ⏱ when using Xrender with the NVIDIA proprietary drivers. We’ve published a PPA where NVIDIA GPU users can install a version of Marco that uses Xpresent for optimal performance ⚡
sudo apt-add-repository ppa:ubuntu-mate-dev/marco sudo apt upgrade
Should you want to revert this change you install
ppa-purge and run the
following from a terminal:
sudo ppa-purge -o ubuntu-mate-dev -p marco.
But wait! There’s more! 😲
These reductions in size are after we added three new applications to the default install on Ubuntu MATE: GNOME Clocks, Maps and Weather My family and I 👨👩👧 have found these applications particularly useful and use them regularly on our laptops without having to reach for a phone or tablet.
New additions to the default desktop application in Ubuntu MATE 22.04 LTS
For those of you who like a minimal base platform, then the minimal install option is still available which delivers just the essential Ubuntu MATE Desktop and Firefox browser. You can then build up from there 👷
Packages, packages, packages 📦
It doesn’t matter how you like to consume your Linux 🐧 packages, Ubuntu MATE
has got you covered with PPA, Snap, AppImage and FlatPak support baked in
by default. You’ll find
support Snap and FlatPak and the (ageing)
libfuse2 to support AppImage are all
flatpak is installed, FlatHub is not
enabled by default. To enable FlatHub run the following in a terminal:
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
We’ve also included
snapd-desktop-integration which provides a bridge
between the user’s session and
snapd to integrate theme preferences 🎨 with
snapped apps and can also automatically install snapped themes 👔
All the Yaru themes shipped in Ubuntu MATE are fully snap aware.
Ubuntu MATE 20.10 transitioned to Ayatana Indicators 🚥 As a quick refresher, Ayatana Indicators are a fork of Ubuntu Indicators that aim to be cross-distro compatible and re-usable for any desktop environment 👌
Ubuntu MATE 22.04 LTS comes with Ayatana Indicators 22.2.0 and sees the return of Messages Indicator 📬 to the default install. Ayatana Indicators now provide improved backwards compatibility to Ubuntu Indicators and no longer requires the installation of two sets of libraries, saving RAM, CPU cycles and improving battery endurance 🔋
Ayatana Indicators Settings
To compliment the BlueZ 5.64 protocol stack in Ubuntu, Ubuntu MATE ships Blueman 2.2.4 which offers comprehensive management of Bluetooth devices and much improved pairing compatibility 💙🦷
I also patched
ayatana-indicator-power and Yaru to add
support for battery powered gaming input devices, such as controllers 🎮 and joysticks 🕹
And in case you missed it, the Ubuntu Desktop team added the option to enroll your computer into an Active Directory domain 🔑 during install. Ubuntu MATE has supported the same capability since it was first made available in the 20.10 release.
Raspberry Pi image 🥧
- Should be available very shortly after the release of 22.04.
Accompanying MATE Desktop 1.26.1 and Linux 5.15 are Firefox 99.0, Celluloid 0.20, Evolution 3.44 & LibreOffice 126.96.36.199
See the Ubuntu 22.04 Release Notes for details of all the changes and improvements that Ubuntu MATE benefits from.
